> As an example, I have been looking at CouchDB,
which uses JSON.
> Brief summary of CouchDB:
> Â Â 1. A B-tree manager whose records are JSON
> Â Â 2. Open-source, available from Apache, with
bindings to all common
> Â Â Â http://couchdb.apache.org
> Â Â 3. An HTTP interface for queries and updates,
which uses map-reduce
> Â Â Â to take advantage of as many CPUs as your
server may have.
> Â Â 4. Documented by an O'Reilly book with a draft
available for free:
> Â Â Â http://guide.couchdb.org/draft/index.html
> At the end of this note is a sample JSON _expression_
used by CouchDB.
> Any quoted string could be a URI or it could be raw
data of any length.
> Suppose that you were a programmer working at a
library, and your boss
> asked you to convert the entire library catalog to
Linked Open Data
> and make it available via HTTP.
> If you chose Couch DB, you could
> Â Â 1. Read the O'Reilly book.
> Â Â 2. Download and install CouchDB.
> Â Â 3. Write a trivial program to map each record in
the library catalog
> Â Â Â to a JSON _expression_ very similar to the
> Â Â 4. Write a program to download every record from
> Â Â Â catalog, convert it to JSON, and store it in
> Â Â 5. Write a web page that tells any web master
anywhere in the world
> Â Â Â how to write an HTTP statement for accessing
> With CouchDB, you could finish that job in one
week. Â What could you

> Of course, there is no requirement that the strings
in JSON conform
> to any particular ontology. Â But that is also true
> JSON makes it easy to tag URIs with types. Â In the

in the ontology.
> That's more readable and more compact than RDF.
Â One JSON structure

multiple RDF triples.
